Scalable anonymous disposable desktops (sadd)

ABSTRACT

Information Security and privacy are the most critical aspects of the internet. The majority of the individuals that have access to the Internet have great difficulty understanding the basics of computers and how they work. This limits the ability of Internet users to protect themselves and their information while browsing the internet. With the creation and testing of SADD (Scalable Anonymous Disposable Desktops), Internet users no longer have to worry about protecting their computer or privacy.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority benefit of U.S. Provisional Application No. 62/655,830, filed on Apr. 11, 2018, which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The embodiments disclosed herein relate to an automated system and method for creating self-disposing Virtual Machine instances whose internet connection is routed through the TOR Project's network. More particularly, the created Virtual Machine instances will be disposed of after a certain time period.

BACKGROUND

Virtualization Technology gives users the flexibility to emulate any type of Operating System. For example, emulation allows Windows Operating Systems to run Linux and MAC OS X Operating Systems internally. This emulation is heavily used in Cloud Computing, Cyber-Security, and Business Application Development.

Created by the US Navy, the TOR Project is a free service designed to protect a user's anonymity while browsing the Internet. It does this through a term better known as “onion routing.” Onion Routing cryptographically routes an internet connection through multiple proxies to prevent eavesdropping and traffic analysis attacks or hide the user's IP address. One draw-back is if the software is exploited, the real IP of the user will be shown.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art. In the drawings, the thicknesses of layers and regions are exaggerated for clarity. Like reference numerals in the drawings denote like elements.

Normally when a user is on a public network such as the Internet, there is no anonymity or privacy because the destination website or server would see data coming from the user's IP address. Additionally, when using a VPN, while there may be partial privacy for the user, the destination web site or server would still see data coming from the IP address of the VPN, and it is possible for the user's IP address to be disclosed by the VPN.

In order to address these deficiencies and others, a scalable anonymous disposable desktop (SADD) system and service is disclosed that enables users to anonymously control self disposing desktops. Unlike VPNs, there are no downloads required at a user device, user actions are not logged or recorded, and information may not be required from users to operate the service. According to some embodiments, SADD creates disposable virtual desktops for the users to control. These virtual desktops are destroyed after a user-specified time limit (or provider specified default time limit) and have their own private networks routed through TOR or other anonymity networks. According to some embodiments, this layer of abstraction is what anonymizes the users. Anyone monitoring the user's local area network will think that the users are visiting SADD, while the destination website or server will think the user is using an anonymity network such as TOR. Even if someone were able to break TOR, which is extremely hard to do, they would have to identify users who have no internet fingerprint.

FIG. 1 is a block diagram illustrating a system for scalable anonymous disposable desktops, according to some embodiments. The system 100 may comprise a user device 102, which may be, for example, a device such as a mobile phone, laptop, desktop computer, tablet, or the like. In some embodiments, the user device may be in electronic communication with a scalable anonymous disposable desktop (SADD) application server 101 via a network 120, such as the Internet.

In some embodiments, the SADD application server 101 may comprise a session generator 103 and/or a virtual machine manager 105. The session generator may comprise a module or system that generates a unique session ids for users 102. This helps the SADD application server 101 to know where to send its information. The virtual machine manager may comprise a module or system that creates, modifies, manages, and/or destroys a virtual machine. In some embodiments, the virtual machine may comprise a virtual desktop 107.

In some embodiments, SADD application server 101 may comprise a backend 110, which in turn may comprise one or more backend servers 115 a to 115 n. In some embodiments, one or more backend servers 115 may comprise one or more of the session generator 103 and/or a virtual machine manager 105. In this respect, according to some embodiments, the SADD application server 101 may be scaled to support a plurality of users 102 by utilizing resources of the backend servers 115 of backend 110. In some embodiments, the virtual machine manager 105 and the session generator 103 may be embodied on the same server or device (e.g., SADD application server 101), or distributed across multiple servers or devices (e.g., one or more backend servers 115 a-n of backend 110).

According to some embodiments, the virtual machine manager 105 may be in electronic communication with an anonymous network gateway 109 associated with an anonymity network 130. In some embodiments, the anonymity network 130 comprises TOR. The anonymous network gateway 109 comprises a system or device that can provide access to public network 120 (e.g., the internet) through an anonymity network 130, such as TOR, VPNs, or proxies.

According to some embodiments, the user 102 would gain access to the session generator 101 through a website or computer application hosted by the SADD application server 101. The session generator 109 would generate a session having a session ID, and contact the virtual machine manager 105 with the generated session ID information, user supplied operating system, and a user supplied or system set time-limit. The virtual machine manager 105 may in turn create a virtual machine comprising the virtual desktop 107 with the session ID and operating system type. The virtual machine manager 105 may also start a timer to notify itself of when the virtual machine needs to be destroyed.

The virtual machine manager 105 may also contact the anonymous network gateway 109 and request access to the anonymity network 130, such as a tor network. According to some embodiments, the anonymous network gateway 109 would setup a VLAN per virtual machine to encourage network isolation. This will provide an extra layer of security around all users. Once completed, the anonymous network gateway 109 will reply back to the virtual machine manager 105 with the credentials to the VLAN.

The virtual machine 107 will then connect to that VLAN and send a ready signal back to the session generator 103. The signal would ultimately get sent and displayed to the user 102 along with the generated session ID. The user 102 can then connect to the virtual machine 107 via session id and use it however they please. According to some embodiments, the user 102 may connect to the virtual machine 107, which may in turn anonymously connect to network 120 via network 130.

Upon the virtual machine manager's 105 timer running out, the virtual machine 107 will be destroyed. The virtual machine manager 105 would request that the anonymous network 130 VLAN be destroyed, and optionally display to the user that the session was terminated.

FIG. 2 is a sequence diagram, according to some embodiments. FIG. 2 is a sequence diagram that shows how a user 102 may interact with the SADD system 100, according to some embodiments. FIG. 2 also describes the back-end operations that may occur, according to some embodiments

At 201, the user device 102 transmits to the session generator 103 a request for a unique session. In some embodiments, the request 201 comprises an indication of an operating system, which may comprise, for example, one or more of Ubuntu, Kali Linux, Windows, and/or Whonix. In some embodiments the request 201 further comprises a time-limit specifying the maximum duration for the generated virtual machine comprising a virtual desktop.

At 202, the session generator 103 generates a session. In some embodiments, the generated session has a unique session identifier (ID).

At 205, the session generator 103 transmits to the virtual machine manager 105 a request to create a Virtual Machine. In some embodiments, the request 205 comprises the generated session ID. In some embodiments, the request 205 may further comprise an operating system type, such as the operating system type specified in message 201. In some embodiments, the session generator 103 and/or virtual machine manager 105 may use VirtualBox commands to create a virtual machine.

At 207, the virtual machine manager 105 creates and starts a virtual machine. In some embodiments, the created virtual machine comprises a virtual desktop 107.

At 209, the virtual machine manager 105 starts a timer to notify itself when it is time to delete the created virtual machine.

At 211, the virtual machine manager 105 transmits a request to an anonymous network gateway 109 a request to create a virtual local-area-network (VLAN) connection. In some embodiments, the virtual machine manager 105 and/or the anonymous network gateway 109 utilizes Whonix commands to create a gateway, such as a TOR gateway. In some embodiments, VirtualBox commands are used to create a VLAN.

At 213, the anonymous network gateway 109 creates a VLAN connection. In some embodiments, the VLAN is created to provide isolation to each individual user

At 215, the anonymous network gateway 109 sends a message comprising the VLAN connection information to the virtual machine manager 105 for configuration. The VLAN connection information may comprises, for example, one or more of an IP address of the VLAN, an IP address of a created virtual machine on the VLAN, and an IP address of the created gateway to the anonymity network.

At 217, the virtual machine manager 105 connects to the VLAN using the received VLAN connection information. In some embodiments, the virtual machine manager 105 utilizes VirtualBox commands to connect the virtual machine to the VLAN and/or the virtual machine to the anonymity network gateway.

At 219, the virtual machine manager 105 sends a ready signal to the session generator 103. In some embodiments, the ready signal 219 comprises an IP address to access the virtual machine and a generated session ID to the virtual machine.

At 221, the session generator 103 transmits the ready signal to the user 102.

At 223, the user device 102 transmits a request towards the virtual machine manager 105 connect to the generated virtual machine. In some embodiments, the request comprises the session ID and/or the IP address to access the virtual machine. In some embodiments, noVNC (web based remote desktop access) or other virtual network computing (VNC) software is used to establish a connection to the virtual machine utilizing the session ID such that the user device 102 can send commands to the generated virtual machine 107.

At 225, the virtual machine manager 105 keeps the session alive between the virtual machine (e.g., virtual desktop) and the anonymous network via the anonymous network gateway 109. While the session is alive, the user device 102 may send commands to the virtual machine and/or virtual desktop. In some embodiments, the commands sent by the user device 102 to the virtual machine and/or virtual desktop cause the generated virtual machine 107 to access a public network 120. In some embodiments, the commands from the user device 102 cause the generated virtual machine 107 to access the public network 120 through the anonymity network 130 via the anonymous network gateway 109. In some embodiments, the virtual machine manager keeps the session alive until the timer runs out.

At 227, when the timer runs out, the virtual machine manager 105 destroys the virtual machine. In some embodiments, VirtualBox commands are used to turn off the virtual machine and/or to turn off the anonymous gateway. In some embodiments, secure-delete on Linux may be utilized to destroy all virtual machine files, which may comprise file shredding at the binary level.

At 229, the virtual machine manager 105 transmits a request to the anonymous network gateway 109 to delete the VLAN connection. In some embodiments, the request 229 may comprise one or more VirtualBox commands to delete a VLAN.

At 231, the anonymous network gateway 109 deletes the VLAN.

At 233, the virtual machine manager sends and displays to the user 102 that the session has been terminated.

FIG. 3 is a method, according to some embodiments. Method 300 is a method for providing a user device 102 anonymous access to a network 120. In some embodiments, method 300 may be performed by SADD application server 101.

At step 302, the SADD application server 101 receives a request from the user device 102 to establish a session with a virtual desktop.

At step 304, the SADD application server 101 generates a virtual machine 107 comprising the virtual desktop.

At step 306, the SADD application server 101 establishes an electronic connection between the generated virtual machine 107 and an anonymity network gateway 109, wherein the anonymity network gateway is in electronic communication with the network 120.

At step 308, the SADD application server 101 establishes an electronic connection between the user device 102 and the generated virtual machine 107.

At step 310, the SADD application server 101 sets a time limit, wherein at an expiration of the time limit the generated virtual machine 107 is destroyed.
